Question

Statement-I :
 Acid strength increases in the order given as HF << HCl << HBr << Hl.
Statement II :
 As the size of the elements F, Cl, Br, I increases down the group, the bond strength of HF, HCl,
HBr and Hl decreases and so the acid strength increases.
 In the light of the above statements, choose the correct answer from the options given below.
 (1) Statement I is incorrect but Statement II is true.
 (2) Both Statement I and Statement II are true.
 (3) Both Statement I and Statement II are false.
 (4) Statement I is correct but Statement II is false.

Answer 1

(2) Both Statement I and Statement II are true.

Explaination:::
In hydra acids acidic strength increases an moving down the group as acid easily release H+ and conjugate anion stabilise due to decrease in charge density
